4.4.5 Setting the RS 232 baud rate
The default RS-232 baud rate is 9,600 with LK2 not fitted. Fitting LK2 changes the baud
rate to 2,400 which allows cable lengths up to 60m to be used between readers; 9600 baud is
limited to 15m.
4.4.6 Static Asset Tag Sensitivity
By adjusting switch S9 it is possible to adjust the sensitivity of the reader to Static Asset Tag
movement. So that small movements by say for example the office cleaner will be ignored,
but deliberate attempts to move the asset will be detected. The reader processor resets a
sensitivity counter every 5 seconds, and the global "sensitivity" of all Static Tags is
determined by the number of pulses detected within this interval.
With switch S9 in position 1, the tag's code will be transmitted immediately it is moved (this
is equivalent to 1 pulse count). If this is too sensitive try another higher setting. The standard
setting for the Static Tag is between 3 and 5 counts. The maximum is 7. Positions 8, 9 & 0
should not be used.

PERATION
Personnel type tags (PS-PET-1) are supplied with their batteries not fitted. This is because
they transmit every 0.6 seconds continuosly as soon as the batteries are fitted. Fitting them at
the factory would result in some loss of battery life. Typically they will operate for around
14 months before requiring replacement.
To use the personnel tag, open the hinged transparent top and fit the 2 lithium coin cells with
the + sign uppermost on to the battery contacts. You may find it easier to open the lid by
gently pushing the long sides away from the grey base. Note the tag number which is printed
on the label on the inside. If you wish you can replace the plain white card with any standard
credit card sized business card or photo-ID card. You can also print graphics or text on the
plain white card using a suitable die-sublimation type printer. Contact Newmark or your
supplier for details of suitable types. Now keeping the batteries in position re-close the
hinged lid until it snaps shut. Note that the tag will operate with only battery fitted. This is
because they are connected in parallel.
When replacing the batteries use only the same types e.g. Varta CR2430 or equivalent.
CAUTION!
Batteries may explode or overheat if incorrectly inserted or short-circuited. They contain
lithium which is highly toxic. Dispose of used batteries in a safe and an environmentally
friendly way. DO NOT just throw them in the bin!! Your local authority may be able to
advise on safe disposal. This also applies to used asset tags.
